Nowadays, if you look at the top product launches on marketplaces like WarriorPlus, JVZoo, Clickbank, etc, you'll almost never see that. Instead, the top products seem to be video courses or apps.
The only exception is PLR courses. People mainly buy them not to learn from them, but to resell them (but will enough of their own customers buy them?).
Can someone create text training and compete? I would imagine this would require a good salespage, and the training should be presented as a membership site, not an ebook, to boost the perceived value.
What is your honest opinion?
